-.TH XScreenSaver 1 "20-Jun-99 (3.15)" "X Version 11"
-.SH NAME
-xscreensaver-demo - interactively control the background xscreensaver daemon
-.SH SYNOPSIS
-.B xscreensaver\-demo
-[\-display \fIhost:display.screen\fP] [\-prefs] [\-xrm \fIresources\fP]
-.SH DESCRIPTION
-The \fIxscreensaver\-demo\fP program is a graphical front-end for
-setting the parameters used by the background
-.BR xscreensaver (1)
-daemon.
-It is essentially two things: a tool for editing the \fI~/.xscreensaver\fP
-file; and a tool for demoing the various graphics hacks that
-the \fIxscreensaver\fP daemon will launch.
-
-The main dialog box contains a scrolling list, a text field, and a number
-of buttons.
-
-Double-clicking on one of the programs in the list will run it. The screen
-will go black, and the program will run in full-screen mode, just as it would
-if the \fIxscreensaver\fP daemon had launched it. Clicking the mouse again
-will stop the demo and un-blank the screen, making the dialog box visible
-again.
-
-Single-clicking in the list will place the indicated program and its args
-in the text field to be edited. Edit the arguments and hit return to run
-the program with the parameters you have specified. This will also save
-your changes to your \fI~/.xscreensaver\fP file: so any changes you make
-in this way are persistent.
-
-If one of the lines in the scrolling list begins with the character "-",
-then that means that the program is disabled: \fIxscreensaver\fP will not
-select it to be run (though you can still try it out by clicking on it.)
-Rather than just deleting the programs you don't want to run, you might
-want to disable them in this way instead, so that you can more easily change
-your mind later.
-
-If the line begins with the name of a visual, followed by a colon, then
-that program will only be run on that kind of visual. For example, you can
-specify that a particular program should only be run if color is available,
-and another should only be run in monochrome. See the discussion of
-the \fIprograms\fP parameter in the \fIConfiguration\fP section of the
-.BR xscreensaver (1)
-manual.
-
-The buttons are:
-.TP 8
-.B Run Next
-Clicking this button will run the next program in the list after the
-currently-selected one, and will wrap around to the top when it reaches
-the bottom.
-.TP 8
-.B Run Previous
-Opposite of Run Next; at the top, it wraps around to the bottom.
-.TP 8
-.B Preferences
-This pops up a second dialog box, in which you have the option to
-interactively change most of the screensaver's operational parameters,
-such as its timeouts, and whether it should lock the screen. When you
-click OK, your chosen settings will take effect immediately, and will
-also be saved to the \fI~/.xscreensaver\fP file in your home directory,
-so that the settings will persist next time.
-.TP 8
-.B Quit
-Exits the \fIxscreensaver-demo\fP program. The background \fIxscreensaver\fP
-daemon will continue running as before.
-.P
-The Preferences dialog box lets you change the following settings.
-
-(There are more settings available, but these are the most commonly used
-ones; see the manual for
-.BR xscreensaver (1)
-for other parameters that can be set by editing the \fI~/.xscreensaver\fP
-file, or the X resource database.)
-.TP 8
-.B Saver Timeout
-After the user has been idle this long, the \fIxscreensaver\fP daemon
-will blank the screen.
-.TP 8
-.B Cycle Timeout
-After the screensaver has been running for this long, the currently
-running graphics demo will be killed, and a new one started.
-If this is 0, then the graphics demo will never be changed:
-only one demo will run until the screensaver is deactivated by user
-activity.
-.TP 8
-.B Verbose\
-Whether to print lots of debugging information.
-.TP 8
-.B Install Colormap
-Whether to install a private colormap while the screensaver is active, so
-that the graphics hacks can get as many colors as possible. (This only
-applies when the screen's default visual is being used, since non-default
-visuals get their own colormaps automatically.) This can also be overridden
-on a per-demo basis.
-.TP 8
-.B Fade Colormap
-If selected, then when the screensaver activates, the current contents
-of the screen will fade to black instead of simply winking out. This only
-works on displays with writable colormaps, that is, if the screen's default
-visual is a PseudoColor visual. A fade will also be done when
-switching graphics hacks (when the \fICycle Timeout\fP expires.)
-.TP 8
-.B Unfade Colormap
-The complement to \fIFade Colormap\fP: if selected, then when the screensaver
-deactivates, the original contents of the screen will fade in from black
-instead of appearing immediately. This only works on displays with writable
-colormaps, and when \fIFade Colormap\fP is also selected.
-.TP 8
-.B Fade Duration
-When fading or unfading are selected, this controls how long the fade will
-take.
-.TP 8
-.B Fade Ticks
-This controls how many times a second the colormap will be changed to
-effect a fade. Higher numbers yield smoother fades, but may make the
-fades take longer than the specified number of seconds, if your server
-isn't fast enough to keep up.
-.TP 8
-.B Require Password
-Whether the screen saver should lock the screen when it activates.
-.TP 8
-.B Lock Timeout
-If \fIRequire Password\fP is selected, this controls the length of
-the ``grace period'' between when the screensaver activates, and when the
-screen becomes locked. For example, if this is 0:05:00,
-and \fISaver Timeout\fP is 0:10:00, then after 10 minutes, the screen
-would blank. If there was user activity at 12 minutes, no password
-would be required to un-blank the screen. But, if there was user activity
-at 15 minutes or later (that is, \fILock Timeout\fP minutes after
-activation) then a password would be required. The default is 0, meaning
-that if locking is enabled, then a password will be required as soon as the
-screen blanks.
-.TP 8
-.B Password Timeout
-When the screensaver is prompting for a password, the prompt dialog box will
-stay on the screen for this long before giving up, and reverting to
-screen-saving mode.
-.SH COMMAND-LINE OPTIONS
-.I xscreensaver\-demo
-accepts the following command line options.
-.TP 8
-.B \-display \fIhost:display.screen\fP
-The X display to use. The \fIxscreensaver\-demo\fP program will open its
-window on that display, and also control the \fIxscreensaver\fP daemon that
-is managing that same display.
-.TP 8
-.B \-prefs
-Start up in Preferences mode: this is just like launching the program with
-no arguments, and then pressing the \fIPreferences\fP button.
-.P
-It is important that the \fIxscreensaver\fP and \fIxscreensaver\-demo\fP
-processes be running on the same machine, or at least, on two machines
-that share a file system. When \fIxscreensaver\-demo\fP writes a new version
-of the \fI~/.xscreensaver\fP file, it's important that the \fIxscreensaver\fP
-see that same file. If the two processes are seeing
-different \fI~/.xscreensaver\fP files, things will malfunction.
-.SH ENVIRONMENT
-.PP
-.TP 8
-.B DISPLAY
-to get the default host and display number.
-.TP 8
-.B PATH
-to find the sub-programs to run. However, note that the sub-programs
-are actually launched by the \fIxscreensaver\fP daemon, not
-by \fIxscreensaver-demo\fP itself. So, what matters is what \fB$PATH\fP
-the \fIxscreensaver\fP program sees.
-.TP 8
-.B HOME
-for the directory in which to read and write the \fI.xscreensaver\fP file.
-.TP 8
-.B XENVIRONMENT
-to get the name of a resource file that overrides the global resources
-stored in the RESOURCE_MANAGER property.
